How aeroplane fly?
aeroplane have aerofoil shape (you could find in the internet how does it looks like)wings that have a specific shape that would make it fly. The high velocity at the top of aerofoil will create the low pressure and the low velocity below the aerofoil will create high pressure. thus, the high pressure will push the aeroplane upwards.
Why do wings keep a plane in the air?
As the plane flies through the air, the upper surface of the wing, or aerofoil, is so curved that it creates higher air speed and lower pressure. In other words this lower pressure gives an upwars"lift" to the aerofoil, wheras the air rushing under the aerofoil creates higher air pressure giving an upward "push" to the aerofoil. So both surfaces create upward forces.
Difference between center of pressure and aerodynamic center?
The CP is the average of all the pressures acting on the aerofoil and as such it will change in magnitude and position as the pressure patterns around the aerofoil changes. The biggest change will be because of changes in angle of attack. The AC is a point on the aerofoil that does not move as you change angle of attack. If you imagine a pivot point on the trailing edge then the aerodynamic forces would make the aerofoil pivot leading edge up about that point. If you now imagine the pivot point at the leading edge then the aerodynamic forces will make the areofoil pivot trailing edge up about that point. If that is so, then there must be a point somewhere between the leading edge and the trailing edge where there will be no change in the pitching moment of the aerofoil as the pressure pattern on the aerofoil changes. That is the AC and it is found at about 25% of the chord. The AC is defined as a point on the chord line that : (1) does not move as angle of attack is changed (2) the pitching moment of a wing is always constant about it
What is center of pressure of an airfoil?
Center of pressureThe position on the chord at which the resultant force act is called center of pressure. the position of center of pressure of pressure is usually defined as being certain position of the chord from the leading edge for ordinary angle of light and angle of attack of the aerofoil is increased center of pressure moves forward

What allows planes to fly?
Aerofoil shaped wings and air pressure allows aeroplanes to fly.

The main shape of an airplane?
what do you mean? but I'll give info anyways.. I'll talk about the wing if you're asking about the shape that makes it fly, the aircraft wing has an "aerofoil shape" the shape is made to have high pressure on the bottom part and low pressure on the top part, thus making it float on air.. more info? Google: Aerofoil
What must airplanes do to fly through the air?
In order to fly, airplanes use aerofoil-shaped wings. An aerofoil is a shape that forms higher pressure beneath than above, pushing the plane up. The engine helps to accelerate the aircraft to a high enough speed to overcome gravity.
What does increased CSF pressure lead to?
Increased fluid pressure typically leads to compression of the surrounding neural tissue, which then leads to increased fluid volume
How is pressure increased?
pressure is increased by forcing more of the substance you are using into a set space. pressure can also be increased by a chemical reaction happening in a set space (bad) e.g. coca cola when its shaken.
